Kernrechtsfrage
Whether the revision request met the requirements of Art. 123(2)(a) BGG based on a new medical letter.
Extrahierter Entscheid
No. The alleged fact was not new; it had already been the subject of the original judgment, and the letter was created only after that judgment.
Extrahierte Begründung
Revision requires newly discovered, material facts or evidence that could not have been produced earlier. A later medical report about an already litigated issue is only a new means of proof for an old fact and cannot found revision.
